Abstract
A new method of coating diamond particles was proposed in this paper, that is, using the high temperature generated by the thermal explosion reaction to induce the sublimation of volatile substances in the raw material and then deposit them on the surface of diamond particles to form one coating. The thermal explosion reaction of Mo/Al/B2O3 system was selected as an example. Results showed the high temperature generated by the thermal explosion reaction may induce a certain amount of Al volatilization. Al was deposited on the surface of diamond particles and reacted with trace oxygen in the environment to form Al2O3. Thus, Al–Al2O3 composite was coated on the surface of diamond particles.
